Specification forming part of Letters Patent No.' 198,145, dated December 11A7 18,77 application filed August 24, 1877.

To all whom it may concern:

Be it known that I, SEBASTIAN NEIs, of Sublette, in the county of Lee and State of Illinois,;have invented certain Improvements in Ghurns, as fully described in the following specication.

The nature of my invention relates to improvements in that class of churns which are arranged with reciprocating plungers; and it has forits object to so construct a two-plunger churn that a thorough agitating of the `milk or creani` is accomplished with but little exertion or power, and that it can b e easily taken apart for emptying and cleaning.

The invention consists in the construction and arrangement of the various parts, and in the combination of the same, as pointed out in the claims.

Figure l is an exterior perspective view of the churn. Fig. 2 is a vertical cross-section of the same. Fig. 3 is an elevation of one of the plungerrod stub-ends, and Fig. et is a plan of one of the dashers.

In the drawing, A is the frame, consisting of two upwardly-tapering side frames, a, each having a vertical standard, a', of the bottom cross-bars b b b2, of the upper cross-bars c c1, and of the brace-bar c2, which latter connects to the top ends of the standards a. D is the churn-box, it being a plain square box, having vent d for drawing off the buttermilk, which is closed by awooden stopper. This boX is closely fltted between the two side frames a, resting upon the bottom cross-bars b b1 b2, the formerof which has an upwardly-projecting shoulder for the end of the .box to be placed against, while two studs, e, which project from under the bottom of said box, willenter corre sponding holes in cross-bar b1. The upper edges of the boX are held endwise by the crossbars c and c. 'The cross-bar c1 is loosely joined in the side frames by having notches near its ends, which will lock with similar notches in the side frame, so that it can be lifted oft' for tilting or removing the churn-box from the frame.

F F is atwo-part cover, being fitted tight to the top of box D. Each half-cover has a knob-handle, f, and is slotted for the plunger! rods to pass through. This cover is locked upon the box by two turn-cams, g, `pivoted to the inward sides of the frame-standards a'.

H is a shaft formed with two cranks, pointing to opposite directions, which is journaled in suitable boxes bolted to the edges of standards a', and on one end it has a pinion, h. I is a gear-wheel secured upon a shaft, i, which is also pivoted to the edge of one of the standards, and has crank K, by which it is rotated, whenit will impartV motion to crank-shaftH at an increased velocity. i The plungers consist each of a rod, L, with an X-shaped dasher, l, to its bottom end. The upper end m of said rod is enlarged to form a journal-bearing or stub-end, by which it is coupled to the crank. The extreme end of this stub-end m is cut in two through the center line, so as to have a cap, n. Both the stubend m and cap n have iron straps secured around their edges, which are pivoted to each other at their upper junction, thus forming a hin ge, by which the cap n, is coupled to the stub-end. The strap of cap n is elongated, the projecting portion being slotted to admit the turn-buckle o, by which it is locked and tightened over the crank.

For taking the churn apart, the covers F struction and arrangement for taking it apart,

which is of great convenience, since cleanliness in a dairy is of the utmost importance.

I am aware that I am not the irst to removably secure a churn-box in a frame upon which is mounted the plunger and multiplying-gear for operating the same; and I am also aware that I am not the iirst to construct a two-plun ger churn the plungers of which are reciprocated by a crank-shaft; but my invention is confined to the peculiar construction of the 2. The combination ofthe stub-end m, hinged I cap n, and turn-buckle o, for securing a churnplunger to its crank-shaft, substantially as described and shown.

3. The combination, with the frame A and churn-box D, of the removable bar c1 and the turn-cams g, for holding the churn-box in the frame, substantially as described and shown.
